Les flors emeten compostos orgànics volàtils (VOCs) per tal d'atreure pol·linitzadors i estimular la fecundació creuada. Alguns volàtils florals però juguen altres funcions, com ara la defensa contra els herbívors. [...]
Flowers emit volatile organic compounds (VOCs) to attract pollinators and stimulate reproductive outcrossing. Some floral volatiles can play roles other than attraction, such as defense against herbivores. [...]

9 p, 4.4 MB β-Ocimene, a key floral and foliar volatile involved in multiple interactions between plants and other organisms / Farré Armengol, Gerard (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Filella Cubells, Iolanda (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Llusià Benet, Joan (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
β-Ocimene is a very common plant volatile released in important amounts from the leaves and flowers of many plant species. This acyclic monoterpene can play several biological functions in plants, by potentially affecting floral visitors and also by mediating defensive responses to herbivory. [...]

30 p, 708.9 KB Ozone degrades floral scent and reduces pollinator attraction to flowers / Farré Armengol, Gerard (Centre de Recerca Ecològica i Aplicacions Forestals) ; Filella Cubells, Iolanda (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Llusià Benet, Joan (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
In this work we analyzed the degradation of floral scent volatiles from Brassica nigra by reaction with ozone along a distance gradient and the consequences for pollinator attraction. - For this purpose we used a reaction system comprising three reaction tubes in which we conducted measurements of floral volatiles using a proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS) and GC-MS.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Niinemets, Ülo (Eesti Maaülikool. Institut of Agricultural and Environmental Sciences)
Emissions of volatiles from leaves exhibit temperature dependence on maximums, but the optimum temperatures for the release of floral volatiles and the mechanism(s) of optimising these emissions have not been determined. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The main function of floral emissions of volatile organic compounds (VOCs) in entomophilous plants is to attract pollinators. Floral blends, however, can also contain volatile compounds with defensive functions. [...]

28 p, 483.6 KB Pollination mode determines floral scent / Farré Armengol, Gerard (Centre de Recerca Ecològica i Aplicacions Forestals) ; Filella Cubells, Iolanda (Universitat Autònoma de Barcelona.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The main objective of this study is to determine if the pollination vector influences the potential floral emissions of flowering plants. We hypothesized that flowers pollinated by insects would emit significantly higher amounts of volatile organic compounds (VOCs) and would present a higher diversity of these compounds than flowers pollinated by wind.
